Oakland 3, Boston 2

Athletics 3, Red Sox 2: Brandon Moss homered among three hits and Coco Crisp tripled and scored as host Oakland completed a three-game sweep of Boston.

A.J. Griffin pitched six strong innings and Grant Balfour (2-2) got four outs in relief to pick up the win for the Athletics, who have won four in a row overall to pull back within a game of .500 at 41-42.

Oakland’s victory spoiled a celebration for Red Sox slugger David Ortiz, who became the 49th player in major-league history to reach 400 homers with a solo blast in the fourth.

Moss and Crisp, who combined to drive in two runs in the ninth in a walk-off win on Tuesday, were at it again on Wednesday. Moss, who came up through the Boston system, hit a solo homer - his 10th - off Aaron Cook (2-2) to give Oakland the lead in the second.

Ortiz’s blast tied it and the Red Sox took a 2-1 lead on Adrian Gonzalez’s RBI single in the sixth.

But Moss helped get the tying run in the bottom of that frame, when he doubled with one out and came in to score on Brandon Inge’s two-out double to right.

Crisp, who won a World Series with Boston in 2007, led off the seventh with a triple to center and scored on Jemile Weeks’ single to left.

All-Star Ryan Cook worked the ninth to earn his eighth save.
